LATCH DEVICE.

Specification of Letters Patent.

Patented. Feb. 27, 1906.

Application filed March 1, 1905. Serial No. 247,954-

To all whom it may concern.-

Be it known that I, CALEB C. SHIVE, a citizen of the United States,residing at Frederick, in the county of Comanche, Oklahoma Territory,have invented certain new and useful Im rovements in Latch Devices, ofwhich the following is a specification.

This invention rovides a novel form of lock device particu arly designedfor doors or the like and embodying oppositely-operating latch-bolts,peculiar means for operating the latch-bolts simultaneously, and specialmeans for adjusting the parts of the device whereby the same is readilyadapted for use in connection with doors or similar closures ofdifferent sizes.

For a full description of the invention and the advantages thereof andalso to acquire a knowledge of the details of constructlon of the meansfor efiecting the result reference is to be had to the followingdescription and accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without dearting from thespirit or essential features thereof, still the preferred embodimentthereof is shown in the accompanying drawings, in which- Figure 1 is aperspective view showing the invention applied. Fig. 2 is a verticallongitudinal sectional view. Fig. 3 is a cross-section of the actuator.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the invention, referrmg to the drawings, thenumeral 1 designates the op ositely-operating latch-bolts, and these bots may be arranged vertically of the door or part to which they areapplied, so as to be projected above and below the same in effecting alocking action. The projected ends of the bolts are adapted to entersuitable socket-pieces 2, one of which may be seated in the floor andthe other attached to the upper portion of the door-frame. It will beunderstood that the device may be applied and arranged horizontally tothe part to which it is secured, this being immaterial so far as theworkings of the invention are concerned. The latch-bolts 1 are connectedwith an actuator 3, arranged between the same and substantially securedto the door in any suitable manner. Connecting-rods 4 are preferablyutilized and connect the latch-bolts 1 and the actuator 3, said rodsbeing connected at one end With the actuator, the opposite ends thereofbeing received in sockets 5, formed at the inner ends of the bolts 1 anddetachably secured in these sockets by means of a transverse pin or likemember 6, affording pivotal connection between parts 1 and 4.

The actuator operating the latch-bolts 1 is of a peculiar constructionand comprises spaced plates 7, which are mounted upon a journal-pin 8,projecting outwardly from an attaching member 9, which is secureddirectly to the door or other support by means of fastening-screws orlike devices. The pin 8 passes through the plate 7 of the actuator, theinner plate being formed with a boss 10 projecting outwardly therefrom,which boss is of tubular form, so as to receive the pin 8 aforesaid. Theboss 10 spaces the plates 7 from each other, having a shoulder 10 tosupport the outer plate 7, and in order to secure the parts of theactuator together a nut 1 1 is screwed upon the outer end of the pin 8.An operating lever or handle 12 projects laterally from the outer of theplates 7, so as to be readily grasped in effecting movement of theactuator in operating the bolts 1. The spaced plates 7 of the actuator 3are each provided with a plurality of openings 13 upon opposite sides ofthe pin 8, and these openings are adapted to receive journals 14 ofattaching members 15, which are interposed between the plates 7. Theattaching members 15 are two in number and are each provided withtransverse openings 16 therethrough to receive the end portion of therod 4, connected with a certain one of the latch-bolts 1. The rods 4 areadjustable through the openings 16 of the members 15, and set-screws 17,arranged transversely of the members 16, are adapted to engage the rodsin order to fix the adjustment thereof with relation to the actuator.The adjustable connection afforded between the rods 4 and the actuator 3by the provision of the members 15 is such that the rods may be quicklyadjusted to adapt the device for doors of different sizes, or, ifnecessary, the rods may be entirely detached from the latch-bolts 1 andthe actuator and other rods of requisite len th substituted therefor. Inorder that the lever 12 may be ings are provided, and under normalconditions the members are journaled in diag onally opposite openings inthe plates 7. When so attached, the lever 12 may be thrown in onedirection; but when it is desired to admit of movement of the lever inan opposite direction for the purposes above premised the plates 7 aredetached and the attaching members 15 are placed in other of thediagonally o posite openings 13. The movement of the ever 12 is limitedin order to prevent the rods 4 from coming into contact with the boss10, and thus cause straining of the parts, by means of a projection 18,which is pendent from the under side of the lever 12, said projectionhaving its ends formed with curved recesses 19. The ends of theprojection 18 are adapted to come into contact with one of the rods 4when the lever 12 is movable in either direction, and the lever is thuslimited in its movement, as above mentioned. To cause the latch-bolts 1to move in properlyalined positions, each of said latch bolts passesthrough a guide-plate 20, attached to the door. One or more of theguide-plates 20 may be provided as deemed most suitable, and said platesmay be of any size.

The device above described is very simple in its operation, actuation ofthe lever 12 causing simultaneous movement of the rods 4 in oppositedirections when projecting the bolts 1 from the door. The rods 4 arebrought into alined position approximately when the bolts 1 areprojected from the door, and said rods firmly resist any tendency of thebolts to disengage from the socket members 5 when the lever is in theposition indicated. The movement of the rods is exactly the reverse whenthe lever 12 is actuated to disengage the latch-bolts 1 from the members5.-

Having thus described the invention, what is claimed as new is 1. In alatch device, the combination of oppositely-operated latch-bolts, anactuator comprising spaced plates, attaching members j ournaled betweenthe plates, rods connected with the latch-bolts and having adj ustableconnection with said attaching members, and means for operating theactuator.

2. In a latch device, the combination of oppositely-operatinglatch-bolts, an actuator comprisin spaced p ates, attaching members journaled etween the plates, rods connected with the latch-bolts andhaving adjustable connection with said attaching members, a lever foroperating the actuator, and means for limiting the movement of theactuator relative to the connecting-rods aforesaid.

3. In a latch device, the combination of oppositely-operatinglatch-bolts provided with sockets at one end, an actuator comprisingspaced plates, a journal-pin for the actuator, attaching membersjournaled between the spaced plates of the actuator and havingtransverse openings therethrough, rods having one end received in-thesocket of each latch-bolt, and an opposite end passed through thetransverse opening in an attaching member of the actuator, a set-screwcarried by the attaching members for adjusting the connection of therods therewith, a lever extended from one of the spaced plates of theactuator for operation of the latter, and a projection carried by thelever for limiting the movement thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
